Hi, i've just joined bookmooch and it seems to be the thing I have been looking for all my life!
You sound like me, although I usually have several books on the go at once.
Some recent favourites of mine are:
Oscar and Lucinda. 2 eccentric and wonderful characters get together in Aus and somehow arrange to have an all glass church erected in the middle of nowhere . Oscar is an English clergyman addicted to gambling . Lucinda also gambles obsessively but owns a glass factory at a time when women were seen but not heard.
The Jane Austen book club. Lightweight but a welcome reminder of the way authors such as Austen can reach out to us across time.
Prey by Michael Crichton. I am a big fan of his books but my all time favourite of his is "the first great train robbery. " the film of which I like to watch at least once a year.
Being English I realised most of my favourites would be europe or uk based and might not cross the pond well.
Oryx and Crake by the brilliant and disturbing Margaret Attwood. The sequel to this is excellent too.
